Handle system for transport, dock retention and desktop positioning of a portable medical device

ABSTRACT

Apparatuses and methods are disclosed herein for securely docking portable ultrasound imaging devices and/or other medical equipment to stand heads and other support structures. In some embodiments, a portable imaging device can include a movable carrying handle that enables the user to easily secure the imaging device to a stand head by rotating the handle to engage one or more latch mechanisms on the stand head. The user can quickly remove the imaging device from the stand head for transport to another location by disengaging the one or more latches and rotating the handle in the opposite direction. If the new location lacks a stand head or other docking structure, the user can rotate the handle downwardly to act as a stand that elevates the rear portion of the device to facilitate use on a desktop or other surface.

This application is a divisional of U.S. patent application Ser. No.16/111,195 filed Aug. 23, 2018, which is incorporated herein byreference.

TECHNICAL FIELD

The disclosed technology relates generally to portable medical devicesand systems that can be operably mounted to a stand or wall unit, andmore particularly, the disclosed technology relates to a handle systemfor transport, dock retention, and desktop positioning of ultrasoundimaging devices and other medical devices.

BACKGROUND

Portable medical equipment, such as ultrasound imaging systems, areoften used while being docked to a floor-mounted stand or a wall-mountedstructure, such as a “zero footprint arm.” Moveable stands and zerofootprint arms can provide a range of motion so that the imaging systemcan be advantageously positioned during, for example, a procedure in anoperating room or other hospital setting. In addition, such mountingstructures can also provide electrical connections for recharging theimaging device. In addition to being mountable to a stand or arm, manyimaging systems are also portable and can be easily removed from themounting structure and hand carried to other locations to perform, forexample, diagnostic examinations in locations other than the typicalhospital setting.

Conventional imaging devices typically include latches or similardevices on the support structure (e.g., a floor stand) to secure theimaging device to the support structure for use. One disadvantage ofthis approach, however, is that the location and operation of the latchmay not be readily apparent to the user and, as a result, the user mayinadvertently fail to properly secure the device prior to use. Thisraises the possibility that the device could fall or otherwise bedisplaced during rotation or other movement of the support structure.Accordingly, it would be advantageous to provide portable ultrasoundimaging systems and other portable medical equipment that could beautomatically or otherwise easily secured to the stand or other dockingstructure as a natural consequence of being properly mounted to thestructure. Additionally, it would also be advantageous to provide suchsystems with the ability to be quickly and easily disconnected from thestand and hand carried to another location for use on, e.g., a desktopor other surface for diagnostic or other procedures.

DETAILED DESCRIPTION

The following disclosure describes various embodiments of systems andassociated methods for dock retention, transport and desktop positioningof portable ultrasound imaging devices and other medical equipment. Insome embodiments, the portable ultrasound imaging devices describedherein include a carrying handle and other features that enable them tobe easily used in different configurations and by different types ofusers. For example, in some configurations the device can be docked to amovable floor stand or wall-mounted arm in a hospital room or similarsetting for use during a procedure. In another configuration, the devicecan be easily undocked and carried to another location where it isneeded and placed on virtually any horizontal surface for use.

As described in greater detail below, in some embodiments the deviceincludes a movable handle that provides much of the functionalitydescribed above. When the portable device is placed on a desktop orother flat surface, for example, the handle can be positioned to raisethe rear portion of the device. In those embodiments in which the deviceincludes a display screen pivotally connected to a control panel in aclamshell arrangement, raising the rear portion of the device in theforgoing manner can provide the user with ergonomic access to thecontrol panel and facilitate viewing of the display screen.Additionally, in some embodiments, elevating at least the rear portionof the device above the mounting surface can create an airspace thatfacilitates convective cooling and improved thermal performance of theinternal electrical components (e.g., CPUs, GPUs, etc.). In furtherembodiments, the device can also be securely mounted to a stand head orother support structure by simply repositioning (e.g., rotating) thehandle to automatically engage the handle with one or more engagementfeatures (e.g., latches) on the support structure.

Although embodiments of the present technology are described herein inthe context of ultrasound imaging systems, those of ordinary skill inthe art will appreciate that the disclosed technology can be used withother medical equipment (e.g., patient monitors, defibrillators, EKGmachines, laptop computers, tablets, mobile devices, etc.) and/or otherdevices that may require securable docking systems. Accordingly, unlessexpressly stated otherwise the systems and methods described herein arenot limited to use with ultrasound imaging systems.

In theFigures, identical reference numbers identify identical, or at leastgenerally similar, elements. To facilitate the discussion of anyparticular element, the most significant digit or digits of anyreference number generally refers to the Figure in which that element isfirst introduced. For example, element 110 is first introduced anddiscussed with reference to FIG. 1 .

FIG. 1A is a partially exploded isometric view of an ultrasound imagingsystem 100 having a portable ultrasound imaging device 110 that can besecurely docked to a support structure 120 in accordance withembodiments of the present technology. FIG. 1B is a similar isometricview in which the portable ultrasound imaging device 110 is docked tothe support structure 120 with a corresponding device handle 112 in anun-secured or unlocked position, and FIG. 1C is a correspondingisometric view in which the portable ultrasound imaging device 110 hasbeen opened to position a display 124 for viewing by a user. Referringfirst to FIG. 1A, in the illustrated embodiment the support structure120 is a stand having a stand head 130 configured to operably receiveand securely hold the portable ultrasound imaging device 110. (For easeof reference, the portable ultrasound imaging device 110 may be referredto herein as “ultrasound device 110,” “device 110,” and the like.) Thestand head 130 is mounted to a support 150 (e.g., a vertical member)that is in turn mounted to a base 140. In the illustrated embodiment,the base 140 includes a plurality of outwardly extending legs that caninclude casters 118 to provide mobility to the stand 120.

In some embodiments, the stand head 130 can be pivotally coupled to theupper portion of the support 150 so that it can be positioned (e.g.,manually positioned) at various angles (as shown by arrows R) tofacilitate use of the device 110. In other embodiments, the stand head130 can be fixed relative to the rest of the stand 120. In addition tothe foregoing features, in some embodiments the stand 120 can alsoinclude various attachments, containers, components, etc. that mayfacilitate use of the imaging device 110. Such features can include, forexample, power storage devices (e.g., batteries), dispensers fordisposable hand wipes, gloves, etc., and/or other useful items. Althoughthe support structure 120 is a movable floor stand, the handle systemsand various embodiments thereof described herein are not limited to usewith a floor stand, and accordingly can be used with virtually any typeof support structure including wall mounted support structures (e.g.,zero footprint arms), as well as other movable and fixed floor- orwall-mounted support structures.

In some embodiments, the stand head 130 includes a recess 132 shaped andsized to receive the device 110. The stand head 130 can also include aconnector 134 positioned in the recess 132. The connector 134 can be,for example, a multi-pin connector that mates with a correspondingconnector (not shown in FIG. 1A) located on a bottom surface of thedevice 110 to provide power to the device 110 for operation and/orrecharging. The stand head 130 can also include a first tab 136 a and asecond tab 136 b that project rearwardly from a forward edge portion ofthe recess 132 proximate the opposite sides thereof.

As described in greater detail below, to securely mount the imagingdevice 110 to the stand head 130 in accordance with some embodiments ofthe present technology, the handle 112 is first positioned so that itextends outwardly from the rear edge portion of the device 110 as shownin FIG. 1A. Next, the front edge portion of the device 110 is positionedin the recess 132 so that the tabs 136 a, b are received incorresponding sockets (not shown in FIG. 1A) proximate the bottomsurface of the imaging device 110. The imaging device 110 is thenrotated downwardly toward the stand head 130 until it is received in therecess 132 as shown in FIG. 1B. In some embodiments, the recess 132 isshaped and sized to receive the imaging device 110 in proper alignmentso that the connector 134 on the stand head 130 correctly mates with thecorresponding connector on the lower surface of the imaging device 110.Once the imaging device 110 is mounted to the stand head 130 as shown inFIG. 1B, the handle 112 can be rotated downwardly to securely engage thehandle 112 with the stand head 130 by operation of, e.g., one or latchmechanisms.

Turning next to FIG. 1C, in the illustrated embodiment the imagingdevice 110 includes an upper portion 114 pivotally coupled to a base orlower portion 116 in a clamshell arrangement. This arrangement enablesthe upper portion 114 to be rotated away from the lower portion in aconventional manner to open the imaging device 110. The lower portion116 can include a control panel 122 having, for example, a keypad,touchscreen, and/or other functionality and controls for operation ofthe imaging device 110 by a user in a conventional manner, and the upperportion 114 can include a monitor or display 124 (e.g., an LCD screen)for displaying corresponding ultrasound images for viewing by the user.

FIG. 2A is a top rear isometric view of the imaging device 110 with thehandle 112 in an upper position (which may also be referred to herein asa “disengaged position”), and FIG. 2B is a similar view of the imagingdevice 110 with the handle 112 in a lower position (which may also bereferred to herein as an “engaged position”), in accordance withembodiments of the present technology. As shown in FIG. 2A, in theillustrated embodiment the upper portion 114 includes an upper housing215, and the lower portion 216 includes a lower housing 211 having arear panel 210. The upper housing 215 is pivotally coupled to the lowerhousing 211 by means of a hinge 213 that extends transversally adjacentto the rear panel 210. The handle 112 includes a first end portion 230 aand a second end portion 230 b that are pivotally coupled to the lowerportion 216 of the imaging device 110. In some embodiments, the handle112 can be made from Delrin®, Tritan™ and/or other suitably strong anddurable plastic materials known in the art, and the lower housing 211and the upper housing 215 can be made from a metal casting, such as castmagnesium, aluminum, etc. In other embodiments, the handle 112 and/orthe upper and lower housings 211 and 215 can be made from other suitablematerials known in the art. For example, in some embodiments the handle112 can be made from a metal casting (e.g., an aluminum casting), andthe upper and lower housings 211 and 215 can be made from injectionmolded plastic.

A user can easily grasp the handle 112 to transport the imaging device110 from, e.g., the stand head 130 (FIGS. 1A-1C) to another location foruse on, e.g., a desktop or other horizontal surface. In someembodiments, the handle 112 can be rotated downwardly from the upperposition shown in FIG. 2A to the lower position shown in FIG. 2B beforeoperating the imaging device 110 on a horizontal surface. Setting theimaging device 110 on a desktop or other horizontal surface with thehandle 112 in the lowered position provides a stand which elevates therear portion of the imaging device 110 off the surface. This provides aspace underneath the imaging device 110 that can enable air to convectheat generated by the device 110 away from the device during operation.Additionally, angling the rear portion of the imaging device 110upwardly in the foregoing manner can also position the control panel 122(FIG. 1C) in a favorable orientation for operation by a user.Additionally, in some embodiments the imaging device 110 can include asensor (e.g., a contact switch, proximity switch, etc.; not shown) thatdetects the position of the handle 112 and provides an alarm signal ifthe handle 112 is not in the lower position of FIG. 2B prior to use ofthe imaging device 110. Such a signal can include, for example, a visualsignal provided by an indicator light connected to the sensor, and/or anaudible signal provided by a buzzer or other audible device. The signalcould also be a text message provided via the display 114 prior to useof the imaging device 110. One benefit of such an alarm is that it canincrease the likelihood that the handle 112 will be in the lowerposition before use of the imaging device 110 on a desktop or othersurface, thereby elevating the rear portion of the device 110 for morefavorable cooling during operation. Additionally, the alarm can alertthe user to the fact that the handle 112 is not locked in the lowerposition when mounted to the stand head 130, which could result in thedevice 110 being inadvertently knocked off the stand head 130 in use. Inyet other embodiments, the sensor could alert the user if the handle 112is too hot for handling at any given time.

FIG. 2C is an enlarged, top rear isometric view of a portion of theimaging device 110 with the rear panel 210 (FIG. 2A) removed from thelower housing 211 for purposes of illustrating various featuresassociated with the handle 112. In FIG. 2C, the handle 112 is in theupper position as also shown in FIG. 2A. In the illustrated embodiment,the first end portion 230 a of the handle 112 is pivotally coupled tothe lower portion 116 of the imaging device 110 by a pivot pin 217 thatis held in place by a hinge bracket 214. In some embodiments, the handle112 can include a first detent 224 a and second detent 224 b atequivalent radial distances from the pivot pin 217. The detents 224 a, bcan be spherical depressions in the surface of the handle 112 that areconfigured to receive a ball 218 (e.g., a ball bearing) that is movablypositioned in a bore 220 of the hinge bracket 214. The ball 218 isbiased against the outer surface of the handle 112 by a biasing member222 (e.g., a coil spring). In operation, the biasing member 222 urgesthe ball 220 into the second detent 224 b to firmly hold the handle 112in the upper position with relatively little “slop” or relative movementbetween the handle 112 and the lower portion 116 of the imaging device110. However, when the user wishes to move the handle 112 to the lowerposition shown in the FIG. 2B, the user can apply a downward force tothe handle 112 and overcome the biasing member 222, thereby causing theball 218 to retract into the bore 220 and permit the downward rotationof the handle 112. When the handle 112 arrives at the lower position,the ball 218 drops into the first detent 224 a to hold the handle 112 inthis position until acted on by the user.

The opposite, second end portion 230 b of the handle 112 (FIG. 2A) canbe pivotally coupled to the lower portion 116 using hardware that is atleast generally similar in structure and function to the componentsdescribed above with reference to FIG. 2C. That is, the second endportion 230 b can be pivotally coupled to the lower portion 116 by asecond pivot pin 217 and a second hinge bracket 214. Additionally, thesecond end portion 230 b can also include the ball/detent combinationshown in FIG. 2C to releasably hold the handle 112 in the upper or lowerposition as selected by the user.

In some embodiments, at least one of the handle 112 or the stand head130 can include an engagement feature for securing the imaging device110 to the stand head 130 when the handle 112 is in the lower positionshown in FIG. 2B. For example, in the illustrated embodiment the firstend portion 230 a of the handle 112 includes a first projection 212 aprotruding outwardly therefrom, and the second end portion 230 bincludes a second projection 212 b (not shown in FIG. 2C) extendingoutwardly therefrom in the opposite direction. (The projections 212 a, bcan also be referred to as “nubs,” “protuberances,” “studs,” and thelike.) The projections 212 a, b can have a circular cylinder shape thatprotrudes outwardly from the handle 112 a distance of, e.g., from about0.1 inch to about 0.5 inch, or about 0.25 inch. As described in greaterdetail below, the projections 212 can be configured to engagecorresponding features (e.g., latch mechanisms) on the stand head 130when the handle is 112 is manually rotated downward to the lowerposition shown in FIG. 2B, to thereby “lock” the imaging device 110 tothe stand head 130.

FIG. 2D is a bottom front isometric view of the imaging device 110configured in accordance with an embodiment of the present technology.In some embodiments, the lower housing 211 includes a forward surfaceportion 236 adjacent a bottom surface portion 234. The forward surfaceportion 236 includes a first socket 232 a and second socket 232 bpositioned toward opposite sides thereof. As described in greater detailbelow, the sockets 232 a, b are configured to receive the correspondingtabs 136 a, b (FIG. 1A) on the stand head 130 when the imaging device110 is docked to the stand head 130. The lower portion 116 of theimaging device 110 further includes a connector 228 (e.g., a multi-pinconnector) positioned in a recess 226. As mentioned above with referenceto FIG. 1A and described in greater detail below, the connector 228 isconfigured to mate with the connector 134 on the stand head 130 when theimaging device 110 is mounted to the stand head 130.

FIG. 3 is a bottom rear isometric view of the stand head 130 in whichthe stand head 130 is shown separately from the rest of the stand 120for purposes of illustration. In the illustrated embodiment, the standhead 130 includes a housing 340 having an upper portion 342 a and alower portion 342 b that are mated together. The upper and lowerportions 342 a, b define a rear edge portion of the stand head 130having a cutout or recess 346. The recess 346 is configured to receivethe handle 112 when the imaging device 110 is positioned in the recess132 of the stand head 130 and the handle 112 is rotated downwardly tothe lower position shown in FIG. 2B. In some embodiments, the upper andlower portions 342 a, b of the housing 340 can be manufactured from castmetal, such as die cast aluminum. In other embodiments, the upper andlower portions 342 a, b can be manufactured from other suitablematerials known in the art, including other metals and plasticmaterials, such as injection molded plastic materials.

In the illustrated embodiment, the stand head 130 includes a first latchmechanism 350 a positioned beneath a first edge portion 355 a to oneside of the recess 346, and a second latch mechanism 350 b positionedbeneath a second edge portion 355 b to the opposite side of the recess346. The first latch mechanism 350 a includes a first latch member 352 aoperably coupled to a first release member 354 (e.g., a knob), and thesecond latch mechanism 350 b similarly includes a second latch member352 b operably coupled to a second release member 356 (e.g., a slidablebutton). As described in greater detail below, the latch mechanisms 350a, b are configured to automatically engage the projections 212 a, b,respectively, on the handle 112 (FIG. 2C) when the handle 112 is rotateddownwardly to the lower position shown in FIG. 2B.

FIG. 4A is an enlarged, bottom rear isometric view of a portion of thestand head 130 illustrating the first latch mechanism 350 a in moredetail. FIG. 4B is a top isometric view of the first latch mechanism 350a with the stand head housing 340 removed for purposes of illustration,and FIG. 4C is a similar cross-sectional top isometric view of the firstlatch member 352 a. Referring first to FIGS. 4A and 4C together, thefirst latch member 352 a includes an angled surface portion 353 thatprotrudes outwardly from a sidewall portion 347 of the recess 346beneath the first edge portion 355 a. An opposite end portion of thefirst latch member 352 a can include an elongate slot 474 that houses abiasing member 472 (e.g., a coil spring) that is compressed against thefirst latch member 352 a by a stop 476 that is fixed relative to thestand head housing 340. In some embodiments, the first latch mechanism350 a can further include a locking feature. For example, the firstlatch member 352 a can include a first fastener hole 482 a (e.g., afirst threaded hole) and a second fastener hole 482 b (e.g., a secondthreaded hole). As described in greater detail below, the fastener holes482 a, b can be configured to selectively receive and engage a firstfastener 480 a (e.g., a screw) that is inserted through a correspondingfirst fastener aperture 478 a in the lower portion 342 b of the housing340 to lock the first latch member 352 a in either a latched position oran unlatched position.

Referring to FIGS. 4A and 4B together, in some embodiments the firstlatch mechanism 350 a can further include a first biasing member 460 ahaving an angled surface portion 466 and a curved (e.g., circular)surface portion 464 that is complimentary to the cross-sectional shapeof the first projection 212 a. The angled surface portion 466 ispositioned generally above and adjacent to the angled surface portion353 of the first latch member 352 a, and the curved surface portion 464is positioned generally behind the angled surface portion 353. The firstbiasing member 460 a can further include a base portion 462 that isfastened or otherwise fixedly attached to the housing 340. The biasingmember 460 a can be manufactured from, for example, spring steel so thatthe angled surface portion 466 and the curved surface portion 464resiliently deflect in response to contact by the first projection 212 a(FIG. 20 ).

Referring next to FIGS. 4A-4C together, in operation the angled surfaceportion 353 of the first latch member 352 a is configured to contact thefirst projection 212 a of the handle 112 as the handle 112 is rotateddownwardly from the upper position shown in FIG. 2A to the lowerposition shown in FIG. 2B. As the first projection 212 a contacts theangled surface portion 353, it drives the first latch member 352 aoutwardly in the direction of arrow UL and compresses the biasing member472. After the first projection 212 a moves past the angled surfaceportion 353, the biasing member 472 drives the first latch member 352 aback into its starting position in the direction of arrow L, and thefirst projection 212 a moves into contact with the curved surfaceportion 464 of the first biasing member 460 a. As the first projection212 a moves into this position, it deflects the curved surface portion464 partially out of the way, and the resulting spring force applied bythe first biasing member 460 a helps to retain the first projection 212a, and hence the handle 112, in the lower position.

To release the first projection 212 a and move the handle 112 into theupper position, the user can slide the first release member 354 in thedirection UL. Once the handle 112 has rotated out of the recess 346 andthe projection 212 a is clear of the first latch member 352 a, the usercan release the first release member 354 and let the biasing member 472drive first latch member 352 a back in direction L to the position shownin FIG. 4A, In some embodiments, the user may wish to lock the firstlatch member 352 a in the retracted or unlatched position so that itdoes not engage and secure handle 112 in the lower position. To do so,the user can slide the first release member 354 in the direction UL, andthen insert the first fastener 480 a through the first fastener aperture478 a and threadably engage the first fastener 480 a with the firstthreaded hole 482 a in the first latch member 352 a. Doing so will holdthe first latch member 352 a in the retracted position so that it cannotengage or otherwise restrict rotation of the handle 112 to or from thelowered position. It should be noted, however, that the handle 112 willstill be engaged with the stand head 130 when the handle 112 is in thelower position, even if the latch member 352 a is locked in theunlatched position. The reason for this is that the first edge portion355 a will block the first projection 212 a if the imaging device 110initiates movement upwardly and away from the stand head 130.Conversely, the user may wish to lock the handle 112 in the loweredposition to, for example, prevent the imaging device 110 from beingquickly disengaged and removed from the stand head 130. To do so, theuser can insert the first fastener 480 a through the first fasteneraperture 478 a and engage the second threaded hole 482 b in the firstlatch member 352 a. Doing so will lock the first latch member 352 a inthe position shown in FIG. 4A and prevent a user from moving the firstrelease member 354 in the direction UL. As a result, the user will beprevented from moving the removing the imaging device 110 from the standhead 130 until the fastener 480 a is withdrawn from the second threadedhole 482 b.

FIG. 5 is a bottom rear isometric view of a portion of the stand head130 illustrating the second latch mechanism 350 b configured inaccordance with an embodiment of the present technology. In someembodiments, the second latch member 352 b and the second biasing member460 b can be identical, or at least generally similar in structure andfunction, to the first latch member 352 a and the first biasing member460 a described in detail above, respectively, except that therespective parts are mirror images of each other. Otherwise, the secondlatch member 352 b and the second biasing member 460 b are structurallyand functionally equivalent to the first latch member 352 a and thefirst biasing member 460 a, respectively. Additionally, the second latchmechanism 350 b also includes a release feature (e.g., the secondrelease feature 356) that is operably coupled to the second latch member352 b and functions in the same manner (or at least generally the samemanner) as the first release member 354 of the first latch mechanism 350a (FIG. 4A). In some embodiments, however, the second release feature356 can be less obvious or less conspicuous to a user than the firstrelease member 354 (which can be, for example, a knob, handle, etc. thatprojects outwardly from the housing 340 as shown in FIG. 4A). Forexample, in the illustrated embodiment the second release member 356 isa slidable button or tab with grip features that can be manually movedin the direction of arrow UL from the position shown in FIG. 5 toretract the second latch member 352 b and permit movement of the handle112 from the lower position to the upper position.

Like the first latch mechanism 350 a, in some embodiments the secondlatch mechanism 350 b can also include a locking feature. For example,in the illustrated embodiment the second latch member 352 b can belocked in either the unlatched or latched positions by inserting asecond fastener 480 b (e.g., a screw) through a second fastener aperture478 b in the lower portion 342 b of the housing 340 and threadablyengaging the fastener 480 b with one of two fastener holes (not shown)in the second engagement member 352 b. More specifically, to lock thesecond latch member 352 b in the latched position shown in FIG. 5 , anoperator can insert the second fastener 480 b through the secondfastener aperture 478 b and threadably engage a first adjacent fastenerhole in the second engagement member 352 b. If the handle 112 is in thelower position when this is done, the second projection 212 b on thehandle 112 will be locked in position behind the second engagementmember 352 b and the imaging device 110 will be locked to the stand head130. If the user wishes to unlock the second latch mechanism 350 b sothat the handle 112 can be rotated upwardly and the imaging device 110can be removed from the stand head 130, the user can do so by removingthe fastener 380 b and sliding the second release member 356 in thedirection of arrow UL. If the user then wishes to lock the second latchmechanism 350 b in the open or unlatched position, the user can do so byreinserting the second fastener 480 b through the aperture 478 b whenthe release member 356 is all the way to the left in the direction ofarrow UL and engaging the second fastener 480 b with a second threadedfastener hole (not shown) in the second engagement member 352 b. In someembodiments, by making the second release member 356 less obvious orless conspicuous than the first release member 354, it can provide ameans for an operator of the imaging system 100 to lock the imagingdevice 110 to the stand head 130 in a way that cannot be easilydiscovered by another person wishing to remove the imaging device 110from the stand head 130.

FIG. 6A is a side cross-sectional view illustrating an initial stage ofmounting the imaging device 110 to the stand head 130 in accordance withan embodiment of the present technology. FIGS. 6B and 6C are enlargedside cross-sectional views illustrating engagement of the handle 112with the second latching mechanism 350 b, and FIG. 6D is a correspondingrear view of the handle 112 fully engaged with the latching mechanisms350 a, b in accordance with an embodiment of the present technology.Referring first to Figure GA, the imaging device 110 can be mounted tothe stand head 130 by first inserting the tabs 136 a, 136 b (FIG. 1A) onthe stand head 130 into the corresponding sockets 232 a, b (FIG. 2D) inthe lower portion 116 of the imaging device 110. Next, the imagingdevice 110 is rotated downwardly into the recess 132, thereby mating theelectrical connector 134 on the stand head 130 to the correspondingelectrical connector 228 on the imaging device 110. Referring next toFIGS. 6B and 6C together, once the imaging device 110 is fully seated inthe recess 132, the user can rotate the handle 112 downwardly about thepivot pins 216 a, b into the lower position shown in FIG. 6C. In someembodiments, the handle 112 is configured to rotate through an angle offrom about 45 degrees to about 125 degrees, or about 85 degrees. As thehandle 112 approaches the lower position, the end portions of theprojections 212 a, b contact the angled surfaces on the distal endportions of the corresponding latch members 352 a, b and drive themoutwardly in the direction of arrows UL (FIGS. 4A and 5 ) against thebiasing force of the associated coil springs 472 (FIG. 40 ). Thisenables the projections 212 a, b to move past by the latch members 352a, b as the handle 112 moves into the lower position. Once theprojections 212 a, b pass by the latch members 352 a, b, respectively,the latch members 352 a, b return inwardly to the extended or latchedpositions to trap the corresponding projections 212 a, b and the handle112 in the lower position, as shown in FIGS. 6C and 6D. Additionally,when the handle 112 is in this position the curved surface portions 464of the biasing members 460 a, b receive the corresponding projections212 a, b and resiliently press against them to generally hold them inplace and reduce vibration of the handle 112.

FIG. 7 is a flow diagram of a method 700 of using the imaging device 110and stand head 130 described in detail above. In block 702, the user canelect the manner in which they wish to use the imaging device 110. Forexample, the user can elect to use the imaging device 110 in a “grab andgo” configuration by retracting both of the latch members 352 a, b andlocking them in the unlatched positions using the correspondingfasteners 480 a and 480 b (see e.g., FIGS. 4A and 5 ). Thisconfiguration enables the user to operably position the imaging device110 on the stand head 130 and rotate the handle 112 downwardly into thelower position without engaging the latch members 352 a, b. It should benoted, however, that even though the handle 112 is not engaged withlatch members 352 a, b in this configuration, the handle 112 is stillengaged with the stand head 130 by virtue of the projections 212 a, bextending underneath the corresponding edge portions 355 a, b of therecess 346 in the stand head 130 (FIGS. 4A and 5 ). When the projections212 a, b are in this position, the corresponding edge portions 355 a, bblock the projections 212 a, b from passing if the imaging device 110starts moving away from the stand head 130. Thus, the imaging device 110will still be secured to the stand head 130 and prevented from becomingdislodged in this configuration. The user can then use the imagingdevice 110 while it is docked to the stand head 130. But since thehandle 112 will not be locked in the lowered position, the user canquickly “grab” the handle 112, rotate it to the upper position, andremove the imaging device 110 from the stand head 130 to “go” to anotherlocation where the device is needed.

Alternatively, the user may wish to use the imaging device 110 in a“safe” configuration in which the handle 112 is automatically latched tothe stand head 130 when the user moves the handle 112 into the lowerposition. In some embodiments, the user can accomplish this by manuallyretracting the second latch member 352 b and locking it in the unlatchedposition with the second fastener 480 b, but not engaging the fastener480 a with the first latch member 352 a so that the first latch member352 a will automatically engage the first projection 212 a when thehandle 112 is rotated into the lower position as described in detailabove. When the handle 112 is engaged with first latch mechanism 350 ain this manner, the imaging device 110 is in a “safe” configurationbecause it cannot be removed from the stand head 130 until the usermanually disengages the handle 112 by retracting the first latch member352 a away from the first projection 212 a and rotating the handle 112upwardly as described above.

As another alternative, the user may wish to use the imaging device 110in an “anti-theft” configuration in which it is “locked” to the standhead 130. In some embodiments, this can be accomplished by locking thefirst latch member 352 a in the closed or latched position with thefirst fastener 480 a (FIG. 4A), and/or locking the second latch member352 b in the latched position with the second fastener 480 b (FIG. 5 )as described above after the handle 112 has been engaged by the latchmechanisms 350 a, b. In this configuration, the imaging device 110cannot be removed from the stand head 130 until both fasteners 480 a, bhave been removed, the latch members 352 a, b have been manuallyretracted, and the handle 112 has been rotated away from the stand head130.

In decision block 704, the user can determine how they wish to use theimaging device 110, and in block 706 the user positions the latchmechanisms 350 a, b on the stand head 130 in the appropriate way.Accordingly, it will be appreciated that the various features of thehandle 112 and the latch mechanisms 350 a, b described herein enable theimaging device 110 to be used in a number of different convenientconfigurations in accordance with the present technology.
